I'm not sure I understand how, if the wifi receiver is turned off,
the laptop receives any packets that are intended to (incidentally)
turn it back on and connect to it.
I don't have much experience with sleep states. When my laptop is bone
idle (open, screen blanked, kbd unlit, no logins, on battery), iwd
still scans the wifi every minute, and ping returns are still instant.
I presume this is the state known as S0.
When I close the lid, it sleeps (I presume it's S3 as there's no swap;
much activity occurs, and is logged, when the lid is reopened). Ping
gets no replies.
S1 and S2 are the mystery ones for me, as I have no idea how to
enter/leave them. I suspect they may be the states where people post
about their (non-builtin) keyboards and mice not waking them up.

Is this perhaps something that DEs do, along with screensavers and
screen locking. (I don't know whether the OP installs one; I don't.
Perhaps that's why I've not encountered S1/S2.)
